چکیده
A 4-year-old Japanese boy presented with cystic lesions on the ventral midline of the penis from birth. Examination of his genitalia revealed multilobulated, freely mobile, cystic papules, 2 ± 4 mm in diameter, on the ventral surface of the penis from the frenulum to the anus. These cysts were translucent and brown ± black in color (Fig. 1). One large cystic lesion was surgically removed for histopathological examination. An electrodesiccation was carried out for the remainder of the lesions.
